SPINNING-FRAME.

FPECIFIGATION forming part of Letters Patent No. 338,216, dated March 16, 1886.

Application tiled November 17, 1883. Serial No. 112,023. (No model.)

To all whom, it may concern:

Be it known that I, JOHN E. ATWOOD, of Stonington, in the county ot' New London and State ot' Connecticut, have invented anew and useful Improvement in Spinning-Frames, of which the following is a specitication.

My invention relates to the spindle-driving mechanism ot' spinning-frames, including the uniting of drivingbands whereby the spindles are driven.

The invention consists in the combination, with a driving-pulley and a guide and tension pulley having parallel axes and supports for the driving-pulley, the guide and tension pulley being arranged below the driving-pulley, of two spindles arranged at opposite sides 'of said pulleys and having their whirls in a horizontal plane about midway vertically between said pulleys, two driving-bands, one for each spindle and each encircling both ot' said pulleys and the whirl of a spindle and comprising two portions, which extend horizontally between the said whirl and adjacent sides ot' said pulleys, and a portion extending directly from one pulley to the other and passing between the two horizontal portions of the band, and bearings wherein the said guide and tension pulley is capable of rising and falling, the guide and tension pulley serving to maintain a proper' tension on the bands and accommodate itselt' to the length thereof and to properly direct the portions of the,

bands. By this combination ot' parts I am enabled to use a very long band in a narrow spinning-frame without danger of any portion of the band rubbing or chan'ng on other portions, and to take up anystretch in the band and keep it under proper tension.

The invention also consists in various novel details in the construction of the boxes for the shaft, whereon are placed the guide and tension pulleys above described, and in a novel manner ot' combining the said boxes with bearings, wherein they may move vertically.

The invention also consists in a novel construction of boxes for a shaft whereon the several spindle-driving pulleys are placed, and in a novel lnanner ot' combining said boxes with the frame ot` the machine.

The invention also consists in a tubular driving-band composed of Iibrous material having one end portion entered directly into the other extreme end thereof and sheathed or teleseoped within the other end portion without looping or tying, and additionally secured together by sewing through both end Y portions.

In the accompanying drawings, Figure 1 is a transverse vertical section of such portions of a spinning-frame as are necessary to illustrate my invention, said frame having a row of spindles on each side, the band for driving the spindle on the left side of the machine only being shown and the band for driving the spindle on the right -side of the machine being omitted for the sake of clearer illustration. Fig. 2 represents the spindle, which is on the right-hand side of Fig. 1, with the band and pulleys necessary to drive it. Fig. 3 is an inverted plan of the driviug-pulley and guide or tension pulley employedin driving the two spindles, which are opposite each other in the machine, together with the two driving-bands and a horizontal section of the spindle-whirls around which said two bands pass. Fig. 4 is a. vertical section of a portion of the spinning-frame in a plane lengthwise thereof, the two shafts on which are the driving-pulleys and guide and tension pulleys being broken to reduce the length ot' the ligure. Fig. 5 is a horizontal section on the dotted line x x, Fig. 4. Fig. 6 is a* perspective view of the two end portions of a driving-band and a tool employed to unite them, said figure illustrating the operation of uniting. the end portions; and Fig. 7 is a side view of the end portions after they are united.

Similar letters of reference designate corresponding parts in all the figures.

A designates one of the end standards of the spinning-trame, and B is one ot' the intermediate supports wherein are arranged bearings for the shafts, which extend lengthwise of the machine. Any number of these intermediate supports may be provided between the two end standards. chine are spindle-rails, each consisting of a pair of parallel rods or tubes, C, to which the intermediatesupports,B,and the spindle-sup; porting brackets C are secured, substantially as shown and described in my application for Letters Patent tiled July 17, 1883, and of which the serial number is 101,042.

On opposite sides of the may ICD kss

D designates the spindles, which are arranged in two rows on opposite sides of the machine and which are provided with the usual whirls, a.

E E' designate the spindle-driving bands, of which there is a separate one for each spindle, and which each encircle a driving-pulley, F, a guide and tension pulley, G, and the whirl a of a spindle. There is one drivingpulley, F, and a guide and tension pulley, G, for the two spindles j which are opposite each other in the machine.

All the driving-pulleys, of which there are as many as there are pairs of spindles, are arranged on' a driving-shaft, F', which carries at one end a pulley, F2, for the reception ofa driving-belt; but obviously a long driving drum or cylinder might be substituted for separate driving-pulleys, as is often done in spinning-frames, and such a cylinder would be the equivalent of the driving-pulleys. The driving-shaft F rotates in bearings or boxes b xed upon or formed integral with the end standards, A butthe boxes Biu which the shaft is mounted at theintermediate supports, B,are so constructed and connected with said supports that they will readily adapt or adjust themselves to the line of the shaft, while they are held against turning or shift-ing endwise.

By referring to Figs. l. and 4 it will be seen that the box B,here shown,is of circular form and is provided at the under side with a downward projection, c, while near the middle of its lengt-h are other projections or swells, d, which extend partly around t-he box, asshown in dotted lines, and are separated by a distance about equal to the thickness ofthe sup port B. The box B is arranged in an opening, B2, in the support B, which is slightly larger than the box, so that the box, with its projections or swells d, may be introduced endwise through the openings. When the box is in place it rests upon the two bearing-surfaces e e, formed by the lower edge of the opening B, as shown in Fig. 1. Its projection c enters a notch or recess, c', in the support B.`whereby the box is held against turning, and the two projections or swells d straddle the support B, as shown in Fig. 4, and hold the box against moving endwise out of the opening B.

The construction of the box B' and the manner in which it is held in place is advantaygeous, because, it dispenses with all bolts or other securing devices, and allows the box to readily adjust itself to the shaft, and also because it enables these parts to be assembled and applied to each other with but little llabor and expense.

Below and parallel with the shaft F is a second shaft, G', on which are secured a number of the aforesaid guide and tension pulleys G, and this shaft is so supported that it, with all the guide and tension pulleys which it carries, is capable of moving upward or downward to a limited extent, and for a purpose hereinafter described.

Atthe intermediate supports, B, the shaft G' is fitted to boxes G2, which are square-or ilat sided for a portion of their length, as shown at f in the horizontal section, Fig. 5. In the intermediate support, B, is an elongated opening,f, to which the square portionfof the box G2 is iitted, and in which said box may move up and down, the box being held against turning by the square portionf. To the side of the support B is adjustably secured a bracket or hanger, B3, which has also an elongated opening, f2, in which the box is received. The bracket or hanger B3, forms a stop to limit the downward movement of the shaft G', and as it is secured to the support B by the screw or or hanger may be adj usted downward, so as to arrest the downward movement of the shaft G' at any desired point.

Upon the side ot' the box G2 is a projection, g2, (shown in Fig. 5 and dotted in Fig. 1,) which is received between the support B and the bracket or hanger B, as shown in Fig. 5. The adjacent sides of the support B and the bracket or hanger B3 therefore form stops to the projection g and hold the box G2 against movement end wise.

In order to hold the shaft G' against movement endwise in the boxes G, I apply to the end of the shaft an end box or cap, G3, (shown in Fig. 4,) which is received in an elongated opening, 72 in the end standard, A. To the outer side of said end standard a bracket, A', is secured by a screw, g, passing through a slot, g', and in this bracket is fixed a set-screw, h', which bears against the end box or cap, G, and holds the shaft G against longitudinal movement.

As the bracket A' is adj ustably secu-red to the side of the end standard, it may be raised or lowered to bring the set-screw It opposite theend box, G3, whatever be its position vertically, and there secured. On the bracket A' is a lip or shoulder, h2, which forms a stop to limit the downward movement of the box G3 and shaft G.

I will now describe the arrangement of the drivingbands and the method of uniting their ends: The band E (shown in Fig. 1) drives a spindle on the one side ofthe machine, and the band E (shown in Fig. 2) drives an opposite spindle on the other side of the machine. Both these bands encircle the same drivingpulley, F, and guide and tension pulley, G; but I have shown the band E' in a separate View, for the sake of clearer illustration. A description of the passage of one band will apply to both. The whirl a of the spindle is in a horizontal plane about midway between the two pulleys F G and the bands E E'. Each comprise two portions, t' t', which extend horizontally between the whirl and adjacent sides of the pulleys F G, and a portion, i', which extends directly frorn one pulley to the other, and which passes between the two horizontal portions z' i. Each guide and tension pulley G is provided with tlangesj, which are placed at a distance apart less thanthe diameter of a bolt g passing through the slot g' the bracket IOS spindle-whirl, a, and these flanges prevent the portion irotl the bandgfrom rubbing or chang on the horizontal portions t i ofthe band.

From the foregoing description it will be seen that each guide and tension pulley is hung in the two bands which encircle it, and

the weight of all the guide and tension pnl-- leys, with their shaft and its boXes,is supported by the driving-bands and all said'parts can gravitate downward as the bands stretch, as they will do, more or less. It will therefore be seen that the guide and tension pulleys, being hung in the bands, will maintain a proper degree of tension on the bands and accommodate themselves to the length thereof, and also serve to properly direct the portions it' i of the bands. These driving-bands are similar in their arrangement to those shown and described in the application for Letters Patent iiled July 9, 1879, by John E. Atwood and Eugene Atwood, and I here claim such an arrangement of band only when used in connection with a guide and tension 'pulley hung in and sup portedl by the band. I do not, however, desire to be limited in the use ot' my combination ofa driving-pulley and a rising and falling guide and tension pulley to a band encircling the pulleys and whirl, as sho\vn,and comprising the port-ions t t' i.

The method ot' uniting the ends ofthe band, which is tubular, is illustrated by Figs. 6 and 7. They are united by entering one end portion, 7c, directly into the other extreme end, and thus sheathing or telescopingthe end portion, It, wholly within the other end portion, c, without looping or tying, and in uniting them I make use of a needle or tool, H, having an eye, Z, near the point.

In preparing the bands I preferably first stretch them to such a degree that they will stretch but little, it' any more, when in use, and the bands are then cut the uniform length, and are marked near the end k, as shown, at the point s, the length from the point s to the end lo', which is the farther end, being the length which it is desired that the baud should have when its ends are united. The tool or needle His then inserted at the point m and through the end portion 7.a', and protruded therefrom at the point n at a little distance from the extreme end of the portion k. The end portion, 7c, is :now threaded into the eye l, and the tool or needle is withdrawn from the portion k, thereby sheathing or drawing the portion k into said portion k until the mark s on the portion lr is coincident with the end 7c. I prefer to enter the portion k at a little distance from the end ot' the portion k', for then there will be no liability ot' the loose ends or bers ofthe portion 7c being turned back and drawn or tucked into the part k by the entrance ot' the part lc. as would be the case if the part k were entered at the extreme end of the part k. Of course, if the part kis entered at a distance from the eX- treme end of the part k a loose end or tag, o,

will be formed; but this will speedily whip or` wear oli" in the use of the band,`lea'ving the band so uniform and smooth that it is difficult to tell where its ends are united.

It will be seen from Fig. 7 that the band, when its ends areunited, has the mark s at a little distance from the point a, where the part k enters the part k', and ,that said mark '1 is coincident with theextreme end of k. TheV band will then be of the length desired.

When tensionis applied to the band, the

Iam aware that it is y not new to splice a.

wire rope having a hempl'heart or core by unlaying the end portions ot' the strands at the two ends of the rope, then relaying the strands of each end portionv into the scores formed by unlaying the strands of the other end portion o't' rope, and finally .removing from each end portion of rope portions ofthe heart or core, and inseriug thereinto the strands of the other end portion.

Iam aware thatit is notnew to unitethe ends i of a tubular band by inserting each end portion through a transverse perforation formed near the other end ot' the band and then doublingsaid end portion backward on itselfA and sheathing it within the portion ofthe band from which it proceeds. Neither do I claim in my present invention a tubular band having the end portions looped together, and sheathed each within the portion of the band from which it proceeds, as described in Letters Patent No. 296,377, granted April 8,1884, to J. E. Atwood and E. Atwood.

My present band differs from those above described, because there is no looping together or tying or interlocking of the two end portions, but one end portion is entered directly into the other extreme end, and is sheathed or telescoped within the other end portion. When the ends are thus united the band is ol' more nearly uniform size throughout-,and there arel no lumps or enlarged portions thereon.

Vhat I claim as my invention, and desire to secure by Letters Patent. is-
